HD74HC76
Dual J-K Flip-Flops (with Preset and Clear)
Description
Each flip-flop has independent J, K, preset, clear, and clock inputs and Q and Q outputs. This device is
edge sensitive to the clock input and change state on the negative going transition of the clock pulse. Clear
and preset are independent of the clock and accomplished by a low logic level on the corresponding input.

High Speed Operation: tpd (Clock to Q) = 21 ns typ (CL = 50 pF)
High Output Current: Fanout of 10 LSTTL Loads
Wide Operating Voltage: VCC = 2 to 6 V
Low Input Current: 1 µA max
Low Quiescent Supply Current: ICC (static) = 2 µA max (Ta = 25°C)

Note: 1. Q and Q will remain HIGH as long as Preset and Clear are Low, but Q and Q are unpredictable,
if Preset and Clear go HIGH simultaneously.
